Third International Conference on Spoken Language Processing (ICSLP 94)
Voyager is a spoken language system that acts as a tourist guide for a limited geographical area. It was initially developed for English and subsequently for Japanese. The kernel of the system is now independent of the language used. In this paper we present the development of the Italian version of this system, stressing which parameters of the system are language independent and which ones are language specific. We present the three essential stages of the development of the Italian voyager. The first stage was data collection: 2367 read and spontaneous sentences have been recorded by 49 native speakers. In the second stage, we defined a set of acoustic models and a lexicon of pronunciations for the summit speech recognizer. The third stage consisted of developing grammar rules and constraints for the semantic parser TINA. The paper presents results in speech recognition, natural language and spoken language system evaluations on an independent test set of 252 sentences spoken by 7 speakers.
